L-Theanine Cures
Modified on Nov 11, 2021
In addition to relaxation, research suggests that L-theanine may have application in the following:
- diminishing symptoms of PMS,
- improving learning performance,
- heightening mental acuity - neurotransmitter,
- promoting concentration,
- acting antagonistically against the paralysis induced by caffeine,
- supporting the immune system,
- lowering blood pressure,
- increasing formation of the inhibitory neurotransmitter GABA, and
- increasing brain dopamine levels among other positive benefits with no known downside.
L-theanine also adds unami (a brothy or savory) taste when added to water, coffee, tea, etc. Decreases bitter taste when added to coffee, tea, and other beverages and foods. Takes effect within 30 minutes after consumption. No known cautions or drug interactions
Stress and Anxiety
Stress and anxiety are debilitating conditions that can shorten life span while lessening performance, well being, and the enjoyment of life. Stress can impair the ability to perform mentally. It may result in reactions to situations that cause enhanced frustration, hostility or even injury. Stress slowly destroys the immune system, lowering resistance to disease and thus allowing degenerative and opportunistic diseases to occur. Stress is a cause of depression. The entire population is subjected to stress. In a 1998 survey, nearly 65 percent of the adult population indicated that they were under great stress. More than 23 million Americans suffer from anxiety illness.
PMS
Studies in cooperation with Taiyo Kagaku Co., The University of Shizuoka, and The Family Planning Institute of Japan have shown that women taking 200 mg L-theanine daily have lower incidence of PMS symptoms. These symptoms include physical, mental, and social symptoms. Overall, a significant alleviation of PMS symptoms by L-theanine was observed.
Brain Chemical May Thwart Ravages of Aging Study
L-theanine appears to have a role in the formation of the inhibitory neurotransmitter Gamma Amino Butyric Acid (GABA). GABA blocks release of the neurotransmitters dopamine and serotonin, playing a key role in the relaxation effect.
